Polytetrafluoroethylene, English called Polytetrafluoroethylene (English abbreviation for Teflon or PTFE), the current domestic mainly called PTFE. It is made of polytetrafluoroethylene polymer compounds, with excellent chemical stability, corrosion resistance, is the world's best corrosion resistance of one of the materials, in addition to molten alkali metal, chlorine trifluoride, five Fluoride and liquid fluoride, the ability of all other chemicals, even in the king of water can not afford to boil, widely used in various needs of acid and alkali and organic solvents occasions. With high sealing, high lubrication non-stick, electrical insulation and good anti-aging ability, excellent temperature (to + 250 ℃ to -180 ℃ temperature long-term work).
Then talk about PTFE in the dust of the specific application
1.PTFE fiber made of needle felt
PTFE fiber needle felt filter has a good acid and alkali resistance, corrosion resistance, high temperature, abrasion resistance and resistance to flexing and other properties, and the material is smooth, hydrophobic, dust can not adhere to the filter surface, widely used in High temperature, high humidity, high viscosity dust industry or with acid and alkali, corrosive chemical gas purification of industrial dust. With the development of environmental protection in China, polytetrafluoroethylene fiber composite needle felt filter in the high temperature flue gas filtration industry has a very important use, with broad application prospects, mainly applicable to the following aspects.
(1) waste incinerator and so on with high humidity, high water content, chemical corrosion, high viscosity dust flue gas purification. In particular, the disposal of waste medical supplies and garbage, can solve the high temperature burning bags, high viscosity dust paste bags, chemical gas corrosion bags and other problems.
(2) boilers with high sulfur coal power plant boilers with acidity, corrosive chemical gas industrial dust purification; mainly with non-stick bags, easy to clean, low running resistance, long service life and so on.
(3) iron and steel smelter blast furnace gas flue gas purification. Mainly to solve the high temperature, high humidity, dew point below the paste bag and high temperature sulfur and other chemical gas corrosion bag problems.
(4) to solve the cement, metallurgy, chemical and other industries of high temperature, high viscosity dust caused by the paste bag, equipment, high running resistance, early embrittlement damage and other difficult problems.
(5) coking furnace, carbon black flue gas purification. Mainly to solve the high temperature, high viscosity dust caused by the cleaning difficulties, after the dew point of the dew point of the oxidation of the filter early embrittlement and other problems.
2.PTFE in the application of film coating
PTFE film surface smooth and resistant to chemical substances, will be covered into the surface of ordinary filter material, played a role in the disposable dust layer, the dust all trapped in the membrane surface, to achieve surface filtration. With the traditional filter material unparalleled superiority. The film filter with a high peel strength, high air permeability, resistance, pore size distribution uniformity and other characteristics, as a dust bag or pleated dust filter cartridge, installed in the dust removal equipment, will be quickly and effectively retained in microns to calculate Ultra-fine dust, dust removal efficiency of 99.99% or more, it is industrial dust filtration and material recovery of the most effective and most economical new filter material. With the other pure high-performance fiber (PPS, glass, P84, aramid) filter the biggest difference is: over time, PTFE will not be aging, accompanied by high temperature gas, corrosive gases, the common role of liquid, PTFE The breaking strength of the base fabric is not attenuated, and the service life is greatly improved.
